Video Signal Driver for DVD Players
Monolithic IC MM1566
Outline
October 25, 2001
This IC is a video signal driver IC that supports 3-ch interlace video developed for DVD players. It includes a low-pass filter that attenuates the noise element during DA conversion, and a 3-channel 6dB amp with 75 driver. In addition, external ESD protection diodes can be reduced by a sag correction pin for reducing output coupling capacitance, and enhancement ot the ESD protection elements for the output pins.
Features
1. Includes a SAG correction pin. 2. Enabled to drive a 3-channel 6dB amp with 75 driver 3. Includes a 4th-order low-pass filter Frequency response: 6.75MHz 1dB / 27MHz - 27dB min. 4. Includes a 6dB amp 5. Includes a power save function 6. S/N=80dB typ. (Y/C mix:74dB typ.) 7. ESD strengh (aerial discharge) of 15kV (IEC standard) 8. Includes mode select pins which correspond to various video signals
